Document Summary

Locomotion related to body weight: greater fat composition of animal or human, less locomotor activity. Sitting and bmi: some relationship between movement and exercise, direct relationship. Problem is expenditure compensation: total metabolic rate goes up during exercise, goes down post exercise, even dips further down. Suppression of energy expenditure: when you push your system opposing force. Total amount of calories is lower than expected from expenditure. During exercise increased rate of production and degradation of: norepinephrine, epinephrine, serotonin, dopamine. So does antidepressants and electroconvulsive shock therapy (est) Depression decreases: depression and intensity of exercise=inverse relationship. Increases turnover of neurotransmitters: anti-depression effect, better food choices, decreases mortality independent of weight. What fuel is the body using to supply energy: at rest: rq~ . 8. Mixture of fat and carb: reflects diet, reflects body composition. Stages of exercise: first 10 seconds: Body has reserve for phosphate bonds supplied by creatine phosphate in muscle. When you don"t have time to wait for atp production.
